While away on a photo shoot, Kendall calls her mom Kris and tells her about the health condition she's been battling called sleep paralysis.

"I'm freaking out because recently I wake up in the middle of the night and I can't move," Kendall says.

When Kendall explains to her mom that it mostly happens on planes, Kris says that she thinks Kendall has "incredible anxiety about traveling" and that she "can't have a fear of getting on a plane" because of her anxiety attacks.

A frustrated Kendall tells her mom, "But it's not...no I'm done arguing with people because everyone says I'm fine, but I don't feel fine. And I promise you one day when I'm rushed to the hospital then you guys are gonna wake up."

Kris tells Kendall that she believes her, she just doesn't want her to live with this "anxious feeling" all the time.

Scott Disick has been enjoying hanging out with Kris, so when she invites him over to swim in the pool, he agrees.

But when he shows up and discovers Kris really invited him over to do water aerobics with all of her friends, he's a little hesitant but eventually joins in.

"I just don't know if this is the most appropriate thing in the world, to be half naked with Kourtney's mom and all of her friends, doing all of these exotic dance moves that you'd see in a strip club," Scott says. "It's a little embarrassing, not gonna lie."

3. Kris Had to Fly From L.A. to London to Get Kendall on a Plane:

Kendall gets very overwhelmed while going over her schedule with Kris and admits she's "scared" to travel that much because of her sleep paralysis.

"I'm scared to fall asleep because it keeps happening to me," Kendall says. "It almost feels like my heart stops."

But Kris tells Kendall, "The nature of what you do for a living and your career is flying around the world. You have designers that have already booked you and are counting on you to show up."

When she hears this, Kendall tells her mom that she thinks her health is more important than her jobs.

"Kendall basically lives on an airplane, so the anxiety on an airplane and the sleep paralysis is a huge problem," Kris says. "Sometimes it's been so bad that she's been paralyzed from even getting on an airplane and I've had to get on a plane, fly from L.A. to London just to get her from London to New York. So it's becoming a real problem."

But when the therapist suggests Kendall mimic the panic attack symptoms she's been having on planes in order to try to manage her anxiety, Kendall shuts it down.

"Oh my God, no this is so scary," Kendall says. "OK pass, I'm not about to actually...Oh my God, no."

Kendall then explains, "The therapist is trying to get me to make a panic attack happen, but every time I think about my anxiety it makes it worse. I wanna get this under control, but not like this."
